Following below are the node.xml contents -

<?xml version = "1.0"?>
<Company>
   <Employee category = "Technical">
      <FirstName>Kennedy</FirstName>
      <LastName>Nkpara</LastName>
      <ContactNo>1234567890</ContactNo>
      <Email>kennedynkpara@xyz.com</Email>
   </Employee>
   
   <Employee category = "Non-Technical">

      <LastName>Francis</LastName>
      <ContactNo>1234667898</ContactNo>
      <Email>stephaniefrancis@xyz.com</Email>

   </Employee>
</Company>


The following example illustrates the usage of the removeNamedItem method -

<!DOCTYPE html>
<html>
   <head>
      <script>
         function loadXMLDoc(filename) {
            if (window.XMLHttpRequest) {
                xhttp = new XMLHttpRequest();
            } else // code for IE5 and IE6 {
                xhttp = new ActiveXObject("Microsoft.XMLHTTP");
            }
            xhttp.open("GET",filename,false);
            xhttp.send();
            return xhttp.responseXML;
         }
      </script>
   </head>
   <body>
      <script>
         xmlDoc = loadXMLDoc("/dom/node.xml");

         y = xmlDoc.getElementsByTagName('Employee')[0].attributes;
         document.write("Name of the attribute removed from 'category' : ")
         document.write(y.removeNamedItem('category').nodeValue);
      </script>
    </body>
</html>

Output

Save this file as namednodemapmethod_removenameditem.html on the server path (this file and node.xml should be on the same path in your server). This gives us the following output below -

Name of the attribute removed from 'category' : Technical
